That’s all he gives us to go on, and while it might reveal some interesting new change in store for the Note 4, it doesn’t do us much good until we can work out what H and TR are supposed to represent.

HSPA+? HDMI? None of the smartphone-related H-words that come to mind seem particularly applicable to the Note 3, nor do any conjure up ideas of corresponding TR-words. Maybe this will be one of those situations where the answer comes to us all of a sudden, making it seem like it should have been so obvious all along, but for now we’re finding ourselves without a strong theory. Got an idea what it might mean? Clue us in down in the comments.

Update: Commenter Josh has what looks like the strongest theory so far: codenames. Whereas the Note 3 was Samsung’s HLTE, the Note 4 may be TRLTE. Maybe not as exciting as a feature tease, but useful in its own right.
